ABSTRACT:
A stagger feeder for a downstream machine such as a power press and the like is disclosed having a structure particularly suited to provide an actual linear path of movement of an activated feed head identical to the effective feed stroke of the material being moved by that feed head. Two movable feed heads are linked together mechanically, and the motion of these feed heads is controlled by a crank mechanism actuated by an indexing mechanism to trigger a pre-pressurized drive cylinder to effect feed stroking. Simplified adjustment of the effective length of the feed stroke is provided by the direct action stagger feeder of this invention to readily accommodate different size blanks in the downstream machine.
